Authentication problem connecting to wifi

Check your wifi password correctly. If you are the owner of the wifi router you are connecting try to press the refresh icon button located on the side of your router.

I assume you're using a secure Wifi connection with a password and it seems like that authentication is not working. You could try using an open wifi access point to eliminate the possibility of this authentication issue.

Authentication often means "password protection" for the specific wifi connection. Usually your software will present a "dialogue" box telling you a password is necessary and give you an opportunity to enter one.

• Can you see your router from the tablet? If not, check to make sure that WIFI is enabled in the Android settings.
• Does your WIFI have a password? If so, you need to enter the password in the Android WIFI settings entry for your router.

turn off 40mhz wide channels
try wpa instead of wpa2
try tkip instead of aes

if all else fails, try wep.

Tablet worked fine on wireless for first two weeks. Now it's showing a line flickering in the wi-fi icon. I checked Ethernet and reset router button. Nothing.

Had same problem - said signal weak although strong on other devices, and hung on authenticating.
Cordless phone on base unit was beside wireless router. Moved unit and turned off phone. Problem disappeared, and signal showed strong.
